A List of Scientific and Engineering Papers by Members of the Staff of the Fisheries Division of the Department of Agriculture and Fisheries 1950-1970Anon. (Department of Agriculture and Fisheries (Fisheries Division), 1972)The Fisheries Division of the Department of Agriculture and Fisheries conducts researches into many aspects of Irish fishes, fishing and fisheries and a considerable number of papers on a wide range of topics have been published over the years in a number of journals including special publications of the Department, namely Irish Fisheries Investigations Series A (Freshwater) and Series B (Marine) and Fishery Leaflets. The present leaflet gives details of papers published by members, or former members, of the Department’s staff since 1950, as a result of their official work or arising there from. In addition to the papers mentioned below members of the Department's staff have contributed to various international bodies other papers, which have not been published subsequently. The list does not, however, include papers prepared by members of the Department's staff, whilst on secondment to semi-state bodies. Some of the authors have now left the service of the Department and details are given as necessary in the following list, Details are also given of the joint authors who were never in the service of the Department.
Sea-trout and their fisheries from the Dublin Fishery DistrictFahy, E. (Department of Fisheries and Forestry, 1981)Age, length and weight data from 440 sea-run trout are described together with data from 339 parr from a small trout stream. Pre-migratory length at age was not influenced by calcium content of nursery streams. Relatively faster growth of certain year classes in particular years was observed. Mean smolt age (2.1 years) was low. Sea run fish averaged at 0.86 sea-winters, contrasting with longer lived sea-trout on the Welsh coast but early maturation was observed in both. The regression coefficient for percentage previous spawners on mean individual weight in the Irish/Celtic Seas was lower than for fish from the Atlantic. The four principal fishing centres are each supplied with sea-trout by two to four small to medium sized rivers. A proportion of the catch is likely to originate in non licensed mullet gear. The annual catch declined from a peak of four tonnes in the 1950s to stabilise at 1.5 tonnes since the 1960s. The decline coincided with an increase in the ratio of draft to drift nets.
